HTTP can be deciphered as HyperText Transfer Protocol, and it acts as an intermediary between you, the user and the site you want to access.

Here is what happens to your requests to connect to a specific site at the moment there is an HTTP proxy server is active:

1. After the client has sent the request to the website he or she wants to access (which generally happens by clicking on the link), the web request is not sent directly to its server. Instead it's sent to an HTTP proxy first;

2. When the request is viewed through the HTTP proxy, it is studied, and all the information is then used to create another request, which will be sent to a web server. It's done in order for you to mask the IP address so the web server cannot really access your private information;

3. After it is determined that the HTTP proxy server forwards your HTTP request through the web server, it is processed by this server in the desired destination so that the response to the client will be developed;

4. After that you will receive an answer of the web server. The server is either allowing you to access the target site or not allowing you.
